A growing body of research has identified fear of visceral sensations as a potential mechanism in the development and maintenance of visceral pain disorders. However, the extent to which such learned fear affects visceroception remains unclear. To address this question, we used a differential fear conditioning paradigm with non-painful esophageal balloon distensions of two different intensities as conditioning stimuli (CSs). The experiment comprised pre-acquisition, acquisition and post-acquisition phases during which participants categorized the CSs with respect to their intensity...

BACKGROUND: Body composition may influence clinical outcomes of certain chemotherapeutic agents. We examined the prognostic significance of skeletal muscle mass and adipose tissue on docetaxel toxicity and overall survival in patients with metastatic castrate resistant prostate cancer (mCRPC). METHODS: A retrospective review of patients medical records with mCRPC, treated with docetaxel was conducted. Body composition parameters (skeletal muscle mass, muscle attenuation [MA], visceral and subcutaneous adipose tissue) were measured at L3 by computed tomography (CT) and defined using previously established cut points...

A non-invasive, auricular percutaneous electrical nerve field stimulation (PENFS) has been suggested to modulate central pain pathways. We investigated the effects of BRIDGE® device on the responses of amygdala and lumbar spinal neurons and the development of post-colitis hyperalgesia. Male Sprague-Dawley rats received intracolonic trinitrobenzene sulfonic acid (TNBS) and PENFS on the same day. Control rats had sham devices. The visceromotor response (VMR) to colon distension and paw withdrawal threshold (PWT) was recorded after 7 days...

REVIEW
Xiulu Ruan, Ken F Mancuso, Alan D Kaye
Oxycodone, a semisynthetic opioid analgesic, is widely used in clinical practice. Oxycodone and morphine seem to be equally effective and equipotent; however, morphine is 10 times more potent than oxycodone when given epidurally. This article provides an updated review of the basic pharmacology of oxycodone with a special focus on pharmacokinetic/pharmacodynamics properties. The controversy regarding oxycodone-mediated effects for visceral pain via agonism and the possible role of peripheral opioid analgesia are discussed in the present investigation in an attempt to propose a plausible explanation to the perplexing question of oxycodone analgesia...

Body composition and poor mental health are risk factors for developing foot pain, but the role of different fat deposits and psychological features related to chronic pain are not well understood. The aim of this study was to investigate the association between body composition, psychological health and foot pain. Eighty-eight women participated in this study: 44 with chronic, disabling foot pain (mean age 55.3 SD 7.0 years, BMI 29.5 SD 6.7 kg/m(2)), and 44 age and BMI matched controls. Disabling foot pain was determined from the functional limitation domain of the Manchester Foot Pain and Disability Index...

REVIEW

Bloating, as a symptom and abdominal distension, as a sign, are both common functional-type complaints and challenging to manage effectively. Individual patients may weight differently the impact of bloating and distension on their well-being. Complaints may range from chronic highly distressing pain to simply annoying and unfashionable protrusion of the abdomen. To avoid mishaps, organic bloating, and distension should always be considered first and appropriated assessed. Functional bloating and distension often present in association with other manifestations of irritable bowel syndrome or functional dyspepsia and in that context patients tend to regard them as most troublesome...

We have demonstrated that activation of 5-HT1A receptors with buspirone promotes visceral analgesia in awake dogs. The administration of 0.035 mg/kg (i.m.) of the drug caused depression of viscero-motor (contraction of the abdominal muscles) and pressor (increase in the heart rate) responses to noxious distension of the large intestine. An increase in the dose to 0.07 and 0.14 mg/kg did not enhance the antinociceptive effect of buspirone but triggered basal tachycardia. The obtained results provide evidence of the inhibitory role of 5-HT1A receptors in modulating visceral pain sensitivity and the possibility of an exciting effect of their activation on the cardiovascular system...

Visceral hyperalgesia refers to increased pain sensation in response to gastrointestinal sensory stimulus. In neonates with neurological impairments, gabapentin has been successfully used as a treatment for visceral hyperalgesia in neonates. The authors describe a preterm infant with myelomeningocele and persistent neuropathic pain that manifested as irritability, hypertonicity, poor weight gain, and feeding intolerance. After exclusion of other etiologies, the diagnosis of visceral hyperalgesia was suspected and the infant was treated with gabapentin...

Situs inversus, an uncommon mirror-image reversal of the major visceral and thoracic organs, is seldom of medical significance. However, the recognition of their unique anatomy is extremely important for those requiring surgical intervention. There are very few reported cases of renal cell carcinoma (RCC) developing in people with situs inversus. To our knowledge, this is the first reported case in Canada. A review of the literature only identified nine published cases worldwide. Here, we review and summarize pertinent information, including patient age and sex, size and location of tumour, method of surgery, and pathology...

BACKGROUND: The mechanisms underlying chronic and persistent pain associated with chronic pancreatitis (CP) are not completely understood. The cholinergic system is one of the major neural pathways of the pancreas. Meanwhile, this system plays an important role in chronic pain. We hypothesized that the high affinity choline transporter CHT1, which is a main determinant of cholinergic signaling capacity, is involved in regulating pain associated with CP. METHODS: CP was induced by intraductal injection of 2% trinitrobenzene sulfonic acid (TNBS) in Sprague-Dawley rats...

Pancreaticoduodenal artery aneurysms (PDAA) are rarely seen among the visceral artery aneurysms (<2%). PDAA is mostly asymptomatic but can be presented with abdominal pain. Embolization can be applied safely with a high success rate however, in some conditions such as when embolization fails or accompanying celiac axis occlusion, open surgery can be performed. We report the successful management of a patient with PDAA and occlusion of the celiac axis with uneventful short and mid term follow up.

BACKGROUND: Visceral artery pseudoaneurysms are relatively rare but have a high mortality rate in case of rupture. Their detection in the last decades is rising due to an increased use of computed tomography and angiography. However, due to the nonspecific nature of the clinical symptoms and signs, diagnosis is often delayed or missed. We describe two cases of patients presenting with nonspecific abdominal complaints and anemia leading to a diagnosis of visceral pseudoaneurysm. Both cases are successfully treated with a different endovascular intervention...

A 29-year-old farmer from central China was sent into the Emergency Department of the Affiliated Hospital of Zhengzhou University. He had a 15-day history of persistent high fever, abdominal distention and pain. The patient was clinically diagnosed as appendicitis and peritonitis, and treated with antibiotics in a local hospital, did not improve. On exploratory laparotomy, the appendicular perforation and peritonitis were seen; appendicectomy were performed, and antibiotics were given. However, high fever and abdominal pain still persisted; intestinal adhesion and obstruction, ascites appeared...

In Visceral Leishmaniasis (VL), the host macrophages generate oxidative stress to destroy the pathogen, while Leishmania combat the harmful effect of radicals by redox homeostasis through its unique trypanothione cascade. L. donovani Ascorbate Peroxidase (LdAPx) is a redox enzyme that regulates trypanothione cascade and detoxify the effect of H2O2 Absence of LdAPx homologue in human makes it an excellent drug target. In this study, the homology model of LdAPx was built including heme and diverse compounds were prefiltered (PAINS, ADMET and Lipinski's 5) thereafter screened against the LdAPx model...

A postpartum female presented with aching abdominal pain as well as persistently elevated blood pressure poorly controlled by medication. Computed tomography angiography was performed and identified an aneursym of the celiac artery proximal to its branching points. Due to symptomatic presentation of the patient and plans of future pregnancy, surgical repair of the aneursym was planned and performed 2 months following initial diagnosis. Celiac artery aneurysms are rare types of visceral artery aneursyms (VAAs) and comprise ~4% of all VAAs...
